TERRENOE H. HUGHES, OF NEW YORK, N. Y.

YARN-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 246,778, datedSeptember 6, 1881,

Application filed June 15, 1881.

To all whom tt may concern:

Be it known that I, TERRENOE H. HUGHES,

of the city, county, and State of New York, e

have invented an Improved Machine for-Printing Yarn, of which thefollowing is a specification.

My improvements relate to machines for printing or coloring the yarnused in weaving carpets.

As usually constructed, such machines consist of a drum, on which theyarn is wound, and a traversing carriage carrying the paintbox androllers by which the color is applied. It is essential that the color bescraped into the yarn after application by the roller.

The object of my invention is to work in the color by pressure, and alsoto effect the winding of the yarn on the drum by automatic mechanism; towhich ends the invention consists in certain novel features ofconstruction, and in devices combined with the ordinary machine, ashereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of themachine, partially sectional. Fig. 2 is an endelevation. Fig. 3 is avertical transverse section on line 00 x of Fig. 1; and Fig. 4 is adetail section, showing the yarn-windin g guide.

Similar letters of reference indicate correspondin g parts.

A is the frame of the machine, carrying the winding-drum B on a shaft,a, to which power is to be applied when the yarn is to be wound, andwhich will be turned by hand during the printing. On the side of drum Bis a ratchet, b, engaged by a pawl to prevent back movement.

0 is the traversing carriage, fitted for movement beneath drum B ontracks I) b by means of cords c, and carrying the printing-rollers d d.The carriage will carry the color-box, omitted from the drawings for thesake of clearness. All these parts, being in common use, do not need amore detailed description.

The yarn-windin g devices, as shown in Figs. 1 and 2, are carried bystandards 61 d, fixed at one end of frame A.

e is a bracket at the lower part of the standards, carrying a reel, f,and g is a slide fitted in grooves for vertical movement at the upperpart of the standards and carrying a reel, h.

a is a cord from slide g, passing over a trio- (No model.)

tion-roller, i, and having a weight, 9, attached to it for drawing theslide upward.

The hank or skein of yarn is to be placed directly upon the reels f h,and will be kept taut by action of the weight. Heretofore it has beenusual to first wind the yarn on a spool and then wind from the spool tothe drum. With the above-described devices the yarn is wound on the drumfrom the skein, and the intermediate winding thus saved.

At the end of frame A, above the standards d, tension-bars 7c are fixedin side brackets, 7t. Above these tension-bars and nearer to the drum isa cross-bar, l, to which is pivoted an arm, m, that carries at its outerend a roller, m. (Shown most clearlyin Fig. 4.) A spring, I, from bar 1to the arm, tends to draw the roller into contact with the drum. Theyarn is passed from bars k to a guide, m and thence downward beneathroller m to the drum. Sufficient tension is thus given to wind the yarnwithout stretching it.

To insure winding of the strands side by side, movement is given to barI by the devices next described. The bar 1 is formed as a rack on itsunder side, and is loosein its sustaining-brackets Z At one side of thedrum a shaft, a, sustained in suitable bearings, extends from thedrum-shaft a to the raclcbar, and carries at its ends pinions a 42 thatengage, respectively, with the rack l and with a worm, a on shaft a. Bythese connections the bar I is moved endwise as the drum revolves, withthe result to carry the yarn slowly across the face of the drum andprevent lapping of the strands.

The improvements in the printing portion of the machine are applied, inconnection with the traversing carriage (J, as follows: On posts 0 0,ateach end of the carriagc,isfitted across shaft, p,from which ascraper-blade, q, of metal, projects upwardly. On the end of the shaftis an arm, 1, weighted to throw the blade q to-' downward, and carriesat its lower end a wiper, u, of sponge or other suitable material, soplaced as to come in contact with the end of scraper q. Thesearrangements are similar at each end of the carriage and at both ends ofthe track, for the reason that the printingrollers lay on the color ateach reciprocation, while the scrapers act alternately.

The operation is as follows: The yarn is first wound upon the drum in asingle layer, after which the printing is done by moving the carriageback and forth, and turning the drum from time to time, to bring theunprinted portions into position above roller d. The usual practice isto place a box of one color on the carriage, and the operator, using thepattern for a guide, turns the drum as required until all the stripes ofthat color are put on. A second color is then put on in the same manner,and so on. \Vith my scraping devices the scraper behind the rollerperforms the work, the other scraper being meanwhile retained out ofcontact by the weighted arm r. As the carriage moves forward the arm 8leaves the tripper t, the scraper is free to assume an upright position,and its end, taking against the sponge u, is wiped. Leaving the sponge,the

end takes against the drum and is turned slightly back until it clearsthe drum and is carried and pressed against the yarn by the weight, thusscraping the color into the yarn. The scraper falls fully forward assoon as it clears the drum, and remains so while the earriage returns,when it is thrown back by its tripper. On such return movement the otherscraper acts as described.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with drum B and thevertically-grooved standards d, of reel 0, slide g, reel h, cord t, andbalance-weight 9, substantially as and for the purposes set forth.

2. The rack-bar l, spring-actuated arm m, carrying roller m, andtension-bars k, substantially as shown and described, in combinationwith the winding-drum B, for operation as set forth.

3. The combination of the shaft n and connections n 71% with thedrum-sl1afta,rack-bar l, and guide-arm m, substantially as shown anddescribed.

4. The rock-shafts p, scrapin g-ton gues q, and weighted arms 1', incombination with the traversing earriage O and yarn-drum B,substantially as shown and described, for operation as set forth.

5. The trippers t, arm 8, shaft 1), weighted arm a, and scrapers q,substantially as shown and described, in combination with the carriage Oand drum B, for operation as specified.

6. The fixed rods to and wipers u, in combination with drum B, carriageC, and scrapers q, substantially as shown and described.
